Description
The present invention relates to a kind of device that utilizes an elastomeric film portion that at least roughly becomes to cover shape to seal single good or packaged goods, described film portion is arranged to fold and stretching by holding back pleat (Raffen), and then it is drawn on single good or packaged goods, the film portion of holding back pleat can be stretched along the Wrap device that single good or packaged goods move and be wrapped on single good or the packaged goods by means of one, and, Wrap device has four tension pin that can move in perpendicular to the plane of parcel direction, it has the supporting member fixing arc of an arc tension element and that extends basically and that extend along the parcel direction basically respectively thereon in this plane, be contained in each corresponding in the zone in the bight of single good to be encapsulated or packaged goods and be wrapped in then on single good or the packaged goods so that will hold back the film portion of pleat.
One-tenth fold setting in a kind of known device film portion that is used for sealing of pattern originally realizes at Wrap device on one's body by holding back pleat, and wherein this film portion is usually directed to an osed top lid at one end.Wrap device has and can be separated from each other mobile tensioning angle for this reason, wherein preferably respectively is provided with a pair of pleat roller and the opposed hold-down roller held back in each bight of Wrap device, and they are rotatably mounted around its horizontal shaft.After Wrap device inserts in the film portion, film portion is clamped in hold-down roller and is arranged to fold with holding back between the pleat roller and by the pleat roller of holding back of driving.Each tensioning angle is separated from each other move being arranged to fold so that on film portion, apply a tension force and film portion is extended, so that and then it can be drawn on single good or packaged goods.Wrap device is descended along single good or packaged goods, and wherein film portion is adjacent to the top of single good or packaged goods and fixes whereby.The fold that is formed in the decline process on the periphery of film portion is launched cumulatively, thus when Wrap device reaches its extreme lower position whole film portion no longer have fold and surround single good or packaged goods and where necessary also encirclement be positioned at base plate below it.
In order to prevent that film portion breaks away from the tensioning angle in the extension process, be fixed in and hold back between pleat roller and the hold-down roller.Advantageously, film portion only is fixed on a very little area, thereby film portion can only be stretched with limitation at the top because otherwise film section branch be damaged.
In the known devices of another kind of pattern, be provided with an independent pleat device and the independent Wrap device held back.Film portion is held back the pleat device by one and is held back pleat also then by an independent movably Wrap device reception, and and then it be wrapped in film portion on single good or the packaged goods.Wrap device has the shaft-like supporting member of directed in opposite in the parcel direction in each bight, its reception is held back the film portion of pleat by holding back the pleat device.And then move along single good or packaged goods by the mobile extension film part of being separated from each other of each supporting member and in order to wrap up Wrap device.Prove that its shortcoming is, it is fixing fully in the drawing process of flexible pipe part, thus oriented film part fully, because its partly landing from the supporting member.
The objective of the invention is, improve targetedly, make its top of oriented film part strongly according to device as described in the preamble.
This purpose reaches like this, anchor fitting like one brake shoe promptly is set on the next door of a tension pin at least, be used in corresponding regional with clamping the be fixed on tension pin of drawing process film portion, described anchor fitting, at least before being about to reach parcel location farthest, be positioned at the zone of fold single good or packaged goods place, single good to be wrapped or packaged goods, particularly film portion in the unfolded zone of this fold, can cling on the film portion from the outside, and rabbet the bight of tension pin at least in part.Anchor fitting before stretching, before being about to reach parcel location farthest, be positioned at least the zone of the fold of the single good to be wrapped at single good or packaged goods place or packaged goods, especially in adjacency by the unfolded zone of the fold film portion that reclines from the outside, thereby with the film portion clamping be fixed between anchor fitting and the tension pin.Whereby can be at the top oriented film part strongly.Be adjacent to single good or packaged goods up to the top of film portion in encapsulation process and just throw off anchor fitting later on once more.Wrap device is moved along single good or packaged goods, thereby can emit fold and surround single good or packaged goods by Wrap device by film portion.
The film portion of single good or packaged goods is tightened in Wrap device and the stretching in Wrap device in case of necessity is satisfactory if almost completely be adjacent to, the film portion that reclines from the outside once more in the zone of fold on single good or packaged goods last to be wrapped that then makes anchor fitting preferably can not break away from tension pin as yet.By the clamping in the zone of such open end in film portion fix, film portion can still be tauted with the state that almost completely wraps up in Wrap device and stretch in addition.
Advantageously, on two relative tension pin next doors of diagonal line an anchor fitting is set respectively.But also fully an anchor fitting might respectively be set on the next door of each tension pin.
Anchor fitting can have a structure that is matched with the tension pin profile in the contact area of tension pin and anchor fitting basically.Film portion is fixed between anchor fitting and the tension pin on a big as far as possible area with clamping, thereby can reaches high stretch ratio at the top.Film portion still can be subjected to strong tightening or even few the stretching soon before finishing encapsulation process simultaneously.
The entering the surface that contacts with film portion and can constitute arc of anchor fitting.
Anchor fitting can move in perpendicular to the plane of parcel direction.Guide rail can for example be set, it allows along the flank movement of two adjacency of single good or packaged goods for this reason.But the combination of the anchor fitting or the different move mode of translation only might be set fully also.
Anchor fitting can move to the direction of corresponding tension pin by means of a rotatable adjusting lever that is provided with.Show that wherein when the anchor fitting hinge type was bearing in adjusting lever, then anchor fitting was matched with the profile of tension pin best.Advise that anchor fitting only can rotate with respect to adjusting lever with a very little degree this moment, contact in anchor fitting anchor fitting rotation and not entering with film portion when the tension pin direction move with the surface of relative set so that prevent.Adjusting lever can for example be hydraulic pressure or compressed-air control.Other actuating device is for example electrically operated also to be possible.
In order to improve the clamping effect, the surface that can contact with film portion of anchor fitting has a surface of improving attaching at least.
This surface can have one here and improve the coating that attaches.
For fear of damaging film portion, this surface can have a soft coating, particularly tongue shape rubber (Moos gummi).
But also might make the surface have alternately that protrude and recessed zone fully.
If Wrap device only for the usefulness of stretching and parcel, then is provided with an independent pleat device of holding back and is used for independently holding back pleat.The back to back stretching of film portion and parcel on single good or packaged goods then by be independent of hold back the pleat device with can realizing of holding back that the pleat device separates along the Wrap device that single good or packaged goods move.Whereby might can to have held back pleat be a film portion by means of holding back the pleat device, the fwd film portion still is wrapped on single good or the packaged goods simultaneously.
Advantageously, the surface that can contact with film portion of anchor fitting is equivalent in drawing process basically for avoiding damaging film portion (considering the technical characterstic and the characteristic of film portion simultaneously) and being the squish area of the desired minimum of extension that reaches.So-called " technical characterstic and characteristic " is understood that thickness, elasticity or the tensility of film portion.For fear of damage, they have influence to the squish area of the requirement of minimum.Also may influence the size of the squish area of minimum requirement in place an order shape, size or the feature of part goods or packaged goods of a stable condition.
Equally still a kind of method of utilizing an elastomeric film portion that at least roughly becomes to cover shape to seal single good or packaged goods of purpose of the present invention, described film portion is arranged to fold and stretching by holding back pleat, and then it is drawn on single good or packaged goods, the film portion of holding back pleat can be stretched along the Wrap device that single good or packaged goods move and be wrapped on single good or the packaged goods by means of one, and wherein Wrap device has four tension pin that can move in perpendicular to the plane of parcel direction, it has the fixing arc of an arc tension element and that extends basically respectively thereon in this plane and point to the supporting member that the parcel direction is extended basically, be contained in each corresponding in the zone in the bight of single good to be encapsulated or packaged goods and be wrapped in then on single good or the packaged goods so that will hold back the film portion of pleat.
In known method, proof disadvantageously, film is at the top, that is the zone that was positioned at single good or packaged goods before being about to reach parcel location farthest can not be stretched before wrapping up fully, because film portion may break away from tension pin in drawing process in this zone.
Therefore the objective of the invention is, improve a kind of method targetedly, make its extension film part strongly.
This purpose reaches like this, promptly, anchor fitting like one brake shoe is set on tension pin next door at least, be used for when stretching the corresponding zone of film portion is fixed on tension pin with clamping, this anchor fitting, at least before being about to reach parcel location farthest, be positioned at single good or packaged goods place, in the zone of the fold of single good to be wrapped or packaged goods, particularly film portion in the unfolded zone of this fold, can cling on the film portion from the outside, and the bight of rabbeting tension pin around at least in part, wherein at least one anchor fitting before film portion stretches for the film portion and cover the film portion of shape and remove from film portion after single good or packaged goods contact of fixedly reclining in the zone of corresponding tension pin at one-tenth roughly.By preventing that fixedly film portion from coming off occasionally partly in the extension process on tension pin, thereby can realize high stretch ratio with clamping.
Advantageously, at least one anchor fitting film portion that can recline in the zone of corresponding tension pin again before film portion is about to leave in the clamping region of anchor fitting after fold is emitted is so that the fixed film part.By the abutting in encapsulation process again and can hold back the pleat film portion and can also stretch to the parcel direction soon before finishing of anchor fitting, thereby can reach high vertical stretch ratio whereby if any requiring.Remove anchor fitting and Wrap device preferably turns back to its original position from film portion once more after this.
The objective of the invention is a kind of method of utilizing an elastomeric film portion that at least roughly becomes to cover shape to seal single good or packaged goods in addition, described film portion is arranged to fold and stretching by holding back pleat, and then on single good or packaged goods, draw, the film portion of holding back pleat can be stretched along the Wrap device that single good or packaged goods move and be wrapped on single good or the packaged goods by means of one, and wherein Wrap device has four tension pin that can move in perpendicular to the plane of parcel direction, it has the fixing arc of an arc tension element and that extends basically respectively thereon in this plane and point to the supporting member that the parcel direction is extended basically, be contained in each corresponding in the zone in the bight of single good to be encapsulated or packaged goods and be wrapped in then on single good or the packaged goods so that will hold back the film portion of pleat.
For film portion fold and that stretch thus, it can be wrapped on single good or the packaged goods, can make things convenient in encapsulation process and without damage emits, and makes film portion become concertina to hold back pleat holding back the pleat process.Hold back fold after the pleat process should be downwards to the single good of packing or packaged goods tilts and directed outward is located over there.The emitting of later no problem of film portion guaranteed in so just uniform location, because can emit fold one by one by Wrap device in this case.
In known method, prove that disadvantageously each fold does not always occupy satisfactory uniform location.Or rather, people usually find that the fold setting partly more or less realizes beyond control.Out of contior fold setting can occur in holds back in the pleat process or also and can occur in the drawing process.
If each fold does not have satisfactory location, then the fold of the fold of close the adjacency that will discharge at least partly, fully superimposed and so clamped and fix even.This situation may cause the damage of film portion, because produce high tension force and therefore may cause hole in film portion when pulling out this fold in film portion.This danger is king-sized in the less film portion of thickness, because in the process of pulling out, may tear film portion easilier, or under the situation of highly bigger single good or packaged goods, thereby because on film portion, hold back the fold that the bigger length of pleat also must form a greater number.
The objective of the invention is, improve said method targetedly, even make it in encapsulation process, under the situation that non-best previous fold constitutes, also can prevent the damage of film portion.
This purpose reaches like this, promptly, to in the first step, draw one first bigger amount for being wrapped in the film portion of holding back pleat on single good or the packaged goods, be reduced to a less amount and in second step, being stretching in of film portion held back in the encapsulation process of film portion on single good or packaged goods of pleat, but make it still can continue parcel.
In this respect, film portion at first is stretched a certain amount of in the first step, and it obviously surpasses the stretching that realizes in the method in common so far.Wherein will stretch as a rule as far as possible and to keep very little and to be restricted to method satisfied implementing desired minimum stretch.For reaching such minimum stretch, the so little amount that in known method, film portion stretched, making when parcel in each side of single good or packaged goods and the comprehensive spacing between the film portion is 3 to 5cm.
According to method of the present invention, with the film portion bigger amount that at first in the first step, stretches, thereby harmonizing about 6 to 10cm with the comprehensive spacing between the relatively large film portion of stretching in each side at single good or packaged goods under this bigger extended state.But bigger amount of tension also is possible.
The respective members of back to back reducing by the extension of film portion in encapsulation process in second step-by making Wrap device, the tension force in the fold of film portion of pleat is held back in the mutual motion-reduction of tension pin usually, make fold whereby, under the situation of not arranged fold location, no longer so clamp and fix by the fold of adjacency doughtily especially, thereby in encapsulation process, can emit film portion no problem rather than cause damage.
In this case may by one local at least delay with resetting of the corresponding scope that still surpasses minimum value that causes cause that tension force reduces and/or one finish reset the time produce less than in the whole Clamping forces of cancellation by freely resetting that time-shift is finished, along with time-shift is set up a tension force once more.
Wherein bigger amount of tension is positioned at beyond the dimension limit of stretching of less amount, and is considered to compare with the stretching of less amount obviously too high in this respect.Measuring of the less amount that stretches, it is equivalent to minimum stretch, not only depends on the geometric configuration of single good or packaged goods.Same other parameter, for example the size of the contact portion that is positioned at film portion of Wrap device also has influence to the measuring of less amount of stretching.
Stretching to less amount reduce can utilize film portion to contact with first above single good or the packaged goods that supporting realizes or just realize up to the moment after in encapsulation process.
In one of method of the present invention possible enforcement, can be in the encapsulation process of film portion on single good or packaged goods continuously, special reducing of realizing equably stretching.
Perhaps, can in the encapsulation process of film portion on single good or packaged goods, be classified to, especially multistage reducing of realizing stretching.When using the reducing an of single-stage finish whole reseting procedures in the past at least major part finished encapsulation process completely and film portion and accepted degree once more by the stretching generation of a less amount.
But if seal the single good or the packaged goods of big height, then has such danger, promptly in film portion finish encapsulation process in the past whole reseting procedures finish, and film portion has reached its degree by the extension maintenance of less amount.The appearance that reduces in multistage realization in this case.
What stretch reduces and can realize in 1/3rd at first of encapsulation process, utilizes this moment film portion to support with contacting of single good or packaged goods and begins encapsulation process.
Preferably from single good or above the packaged goods in 5 to 20cm the spacing, especially reducing of realizing in the spacing of 10cm from single good or above the packaged goods stretching.
Advantageously, the film portion that bigger amount stretches in the first step is fixed by means of at least one anchor fitting, so that the beginning encapsulation process, and, on film portion, remove anchor fitting once more along with stretching in second step is reduced to a less amount.When wrapping up, film portion at first is fixed on the film portion that amount bigger in the first step stretches.Only recline in the above single good or packaged goods of film portion whereby, and each side of single good or packaged goods does not contact with film portion.Since fixing, vertical tension force may in film portion, be produced.Then in the process of the continuation of encapsulation process in second step along with stretching is reduced to a less amount, from film portion, break away from anchor fitting, thus then one by one fold discharge film portion.
Embodiment shown in the accompanying drawing of the present invention below is described.Wherein:
Fig. 1 one tension pin and hold back the lateral plan of the film portion of pleat on it; And
Fig. 2 presses the partial top view of the device of Fig. 1.
In institute's drawings attached, identical or same parts adopt consistent Reference numeral.
Fig. 1 and 2 illustrates the Wrap device 1 of device of the present invention.Not shownly hold back the pleat device what operating process was installed previously.Wrap device 1 has four tension pin 2, and they are arranged on each bight of single good shown in the part or packaged goods 3.
Each tension pin 2 comprises the tubulose tension element 4 that a camber constitutes, and it is positioned one perpendicular in the plane of wrapping up direction 5.
Shaping one roughly becomes the supporting member 6 that dihedral constitutes on each tension element 4, and it is fixed on the underwork 8 by the crossbeam 7 below.
As conspicuous by Fig. 1, the two ends of tension element 4 are connected with corresponding supporting member 6 by means of hound 9.
Installation one pole 10 on crossbeam 7.On this pole 10, be rotatably mounted an adjusting lever 12, fix an anchor fitting 14 by another bearing 13 at its free end by a bearing 11, anchor fitting 14 enter the profile that the surface that contacts with tension pin 2 is suitable for tension pin 2.Constitute arc roughly by the supporting member 6 of tension pin 2 in the embodiment shown, so anchor fitting 14 also has corresponding arc structure.But tension pin 2 is arranged in the height of tension element 4.
Connect a cylinder 15 on adjusting lever 12, it is shown among the figure with long and short dash line, and it can for example relate to an air cylinder or hydraulic actuating cylinder in this respect.
As especially as seen from Figure 2, thereby tension pin 2 and the anchor fitting 14 that is fixed on the crossbeam 7 can move along the longitudinal edge (arrow 16,17) of single good or packaged goods 3.In order to realize that underwork 8 is connected with a guide rail 19 by guide piece 18 along the moving of the direction of arrow 17.By means of the chain 20,21 that is connected on the crossbeam 7 tension pin 2 is moved along the direction of arrow 17.
For the direction of each Wrap device 1 at arrow 23 can move along single good or packaged goods 3, a hydraulic actuating cylinder 24 is set in the embodiment shown, it is connected on the supporting element 22 below.But the structure that also can adopt other is in order to reach along the mobility of the direction of arrow 23.
As shown in FIG., four tension pin 2 embed in the film portion 25 of opening wide downwards.Film portion 25 becomes fold 26 to be placed on the tension pin 2 by holding back pleat.This is realized in unshowned independent holding back in the pleat device to hold back pleat.Film portion 25 by hold back the pleat device with the state of holding back pleat by shown in Wrap device 1 receive.
Hold back each anchor fitting 14 after the film portion 25 of pleat in reception along the direction deflection of the direction of arrow 27, thereby film portion 25 is fixed on the supporting member 6 of tension pin 2 and accordingly between the anchor fitting 14 with clamping to the tension pin 2 that relates to.For fear of damaging film portion 25, the surface that contacts with film portion 25 that enters of anchor fitting 14 has soft coating 28, for example tongue shape rubber.But also can imagine other coating.
After anchor fitting 14 reclined, tension pin 2 was outside, and for example diagonal line is separated from each other motion to the direction of export-oriented arrow 29, thus oriented film part 25.By fixing with clamping, can be at the top, that is the end of sealing formation in this case oriented film part 25 best.
After stretching, Wrap device 1 moves along single good or packaged goods 3 in parcel direction 5.In case the top of film portion 25 is adjacent to single good or packaged goods 3 in the above, just anchor fitting 14 is turned back to position shown in dotted lines in Figure 2.When Wrap device 1 continues to descend, fold 26 is discharged by tension pin 2 cumulatively, thereby whole film portion 25 no longer has fold 26 and surrounds single good or packaged goods 3 when Wrap device reaches its extreme lower position.
For film portion 25 is tightened and where necessary in order along the stretching of parcel direction 5 anchor fitting 14 to be moved on to before film portion 25 is emitted by tension pin 2 fully among Fig. 2 soon once more with the position shown in the solid line along parcel directions 5 last, thus film portion 25 once more by clamp fitting at anchor fitting 14 with accordingly between the tension pin 2.
Make film portion 25 can be best tighten and stretch whereby along parcel direction 5.
Tightening along parcel direction 5 and going back to anchor fitting 14 after the stretching where necessary, and making Wrap device 1 move on to the position shown in its original Fig. 1 in contrast to parcel direction 5 once more, so that receive another film portion of holding back pleat 25.
If fold 26 can not have the location of the downward uniformly and directed outward shown in Fig. 1 after holding back pleat, then will be for being wrapped in the film portion 25 of holding back pleat on single good or the packaged goods one first bigger amount that in the first step, stretches in order without damage to emit film portion 25 suggestion by tension pin 2, be reduced to a less amount and in second step, being stretching in of film portion 25 held back in the encapsulation process of film portion 25 on single good or packaged goods 3 of pleat, but make it still can continue parcel.
The film portion 25 bigger amount that at first in the first step, is stretched thus, thus harmonizing about 6 to 10cm in each side of single good or packaged goods and the comprehensive spacing that stretches between the relatively large film portion 25 under this bigger extended state.But bigger amount of tension also is possible fully.
By second the step in encapsulation process the back to back of stretching of film portion 25 reduce, reduce to hold back the tension force in the fold 26 in the film portion 25 of pleat along the moving of the edge of single good or packaged goods 3 (arrow 16,17) by means of tension pin 2, make fold 26 no longer so clamp and fix by the fold 26 of adjacency doughtily whereby, thereby in encapsulation process, can emit film portion 25 no problem and do not cause damage.
In this respect, can be continuously or be classified to, especially multistage reducing of realizing stretching.
In order not only in the first step, to produce stronger or bigger stretching but also in second step, to produce less stretching (minimum stretch), in a form of implementation, can adopt same member, drive motor for example, its in addition correspondingly control.
It would, of course, also be possible to is provided with two independent members, and for example two drive motor or hydraulic actuating cylinder, one of them member produce the stretching of less amount and realized the stronger stretching that exceeds its scope by another second member.
